SPINNING-SPINDLE.

SPECIFICATION forming part of Letters Patent No. 602,987', dated April 26, 1898.

Application filed November 29, 1897. Serial No. 660,042. (No model.) A

To @LZ whom, it may concern:

Be it known that I, WILLIAM I-IINCHLIEEE, of Huntsville, county of Madison, State of Alabama, have invented an Improvement in Spinning-Spindles, of which the following description, in connection with the accompanying drawing, is a specification, like letters and figures on the drawing representing like parts.

Thisinvention relates to spinning-spindles; and it has for its object the production of simple and efficient means whereby the retainng-hook may overlap the spindle-whirl to a greater extent to obtain a better purchase, with means for preventing accidental withdrawal of the hook and consequent release of the spindle.

The drawing, in elevation an d partly in seotion, represents a spindle with my invention applied thereto.

rlhe spindle S, mounted in any suitable bearing, (not shown,) supported in the case A, threaded to receive the nut B to retain it upon the rail BX, and the whirl YV, attached to the spindle, may be and are of usual con struction.

The case A is provided with a well-known form of oil-reservoir O to admit oil to the interior of the case.

I have herein shown the upturned portion of the reservoir provided on the side toward the spindle with ears cx, (only one being shown,) in which are independently pivoted the reservoir-cover c and the spindle-retaining hook cl. The hook is fulcruined at cl' near its lower end and has a long lip cl2 to extend over the whirl as far as desired, the extended lower end di of the hook bearing against a lugV to limit the inward movement of the hook.

It will be noticed that the cover c, fulcrumed on the ears at c', is extended between the latter to form a detent c2 to within a short disrance of the back of the hook. So long as the oove'ris in closed position the hook cannot be withdrawn, and any upward pull on the spindie cannot possibly throw the hook back to release the whirl and spindle.

When it is desired to release the spindle, the cover is turned up into dotted-line position, so that the detent c2 is moved away from the hook, whereupon the latter can be swung back sufliciently to release the whirl.

While the cover can be lifted independently of and without withdrawing the hook, the latter cannot be moved into inoperative position unless the cover is iirst lifted.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l'. A supporting-ease having an oil-reser vvoir, a spindle-retaining hook, and an independently-mounted cover for the reservoir, provided with a detent to prevent accidental withdrawal of the hook.

2. A spindle-supporting case having an upturned oil-reservoir provided with ears, a reservoir-cover and a spindle-retaining hook, in-

dependently ulcrulned on said ears, and a projecting lug on the cover back of the hook, whereby the latter cannot be withdrawn when the cover is shut.

'In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WILLIAM HINCHLIFFE.
